To all 'whom it may concern Be it known that I, HARRY M. PFLAGER, a citizen of the United States, residingat St. Louis, Missouri, have invented a certam new and useful Improvement in Locomotive-Tender Frames, of which the following is a full, clear, amd exact description, such as will enable others skilled in the art to which 1t appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in

whichn Figure 1 is a vertical section taken longitudinally through the center of the lower portion cfa locomotife tender of my imconstruction.' ig. 2 is a horizontal section taken a proximately on the line 2-2 of Fig. 1 and s owing the tender underframe in plan View.` Fig. 3 isan enlarged transverse section taken a proximately on the line 3;-3 of Fig. 2. 1g. 4 is an enlarged transverse section taken approximately on the line 44 of Fig. 2. n

This invention relates generally to locomotive tenders, and more particularly to the tender underframe, and the arrangement or combination between said underframeand the upper portion or body of the tender.

. e principal object of my invention is to materially lower the center of gravity of the tender and to accomplish this object I propose to practically inclose the entire underframe, which is preferably formed in a single piece, substantiafly within the body or tank portion of the tender thereby forming water space within the underrame.

s tenders are commonl constructed the body of the tender which fyorms the tank or cistern generally rests upon a flooring, which latter rests upon the underframe, and thus the entire water space within the tank or cistern is located wholly and a substantial distance above said uriderframe. In such construction the center of gravity of the tank when full is comparatively high, and in my im ro'ved construction, I propose to close the ottom of the tender underframe, thereby forming a series of communicating water compartments within` the frame between the longitudinally and transversely dis osed members forming said underframe, whlch water compartments' communicate with the main compartment of the tank positioned upon the underframe, which arrangement not only materially lowers the center of gravity of the tender, but provides an exceptlonally strong, rigid, and durable structure.

with the above and other objects in view, my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.

s shown in the drawings, the tender underframe is formed in a single piece and' comprises a pair of flanged side sills 1, end or buiiing sills 2, which are preferably hollow, a pair of bolster members 3, preferably of I-beam shape in cross section, a pair of flanged center sills 4 between the bolster, and a centrally arranged transversely disposed cross sill 5. A pair of vertically disposed longitudinally extendn'g arallel walls 6 extend from one of the end sills 2 to the adjacent bolster 3, and the upper por-` tlons of these walls are united by a horizontally dis osed plate 7, thereby forming a pocket 8 etween said walls 6, which pocket 1s adapted to receive suitable draft rigging. At the opposite end of the underframe, a pair of vertically disposed walls 9' extend between the corresponding bolster and end sill, the upper edges of which walls are unitedby a top plate 10. Formed on the undersldes of the walls 9 and the underside of the corresponding end sill 2 is a housing 11 which is adapted to receive a couplerl shank (not shown.)

I F1xed the undersid'e of the underframe 1n any suitable manner, referably b means of rivets, is a bottom plate 12 which closes al'l of the open spaces between the longitudinally and transversely disposed members forming the underframe, with the exception of the draft rigging pocket 8 and the space between the walls 9 and below the plate 10. Suitable openings, such as 13, are formed through the lower portions of the webs of theV bolster's 3', sills 4 and cr'oss sill 5, for the purpose' of establishing communication between the various spaces in the underframe, thereby permitting the water to circulate or pass from one space or compartment to the other. Formed integral with the lower portion of the cross sill 5 are horizontally disposed plates 14 and 15 to .which are adapted to be fixed the air brake cylinder, auxiliary tank, and other parts usually applied to the underside of the tender. Fixed to the underside's of the holsters 3 are center bearings 16 and sidebearings 17, and fixed to the undersides of the side sills 1 at suitable points are safety chai-n hanger brackets 18. Fixed in any suitable manner to the tops of the side sills 1 and the'tops of the end or buffing sills 2 are the lower edges of the side and end walls 19 and 20 respectively, which form the body or tank of the tender. This body or tank is of the usual or any well' known construction and is provided at one end with a fuel compartment 21. Located on the interior of the tank above the underframe is a series of transversely disposed bulk heads 22. By closing the underside 0f the underframe with a plate and fitting the lower edges of the side and end walls ofthe tank to the side and end sills of the underframe, practically the entire space within the underframe between the longitudinally and transversely disposed members thereof is utilized as water space and as such space is of considerable area, a comparatively large amount of water can be accommodated, and thus the center of gravity of the tender is materially lowered.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved tender can be made and substituted for those herein shown and described without departing from` the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:

1. In a locomotive tender a tank and an underframe upon which the tank is mounted which underframe constitutes a part of t-he tank.

2. A locomotive tender comprising a tank, an underframe therefor, which underframe is located above the bottom plate of the tank.
